ABSTRACT:
A wiper which clamps on cable conduit and fits over end cup seals has an opening which loosely receives a sliding cable rod to scrape debris from the rod before portions of the rod enter the seal. The wiper is formed from a strip of spring steel pierced centrally to receive the rod. The piercing forms a slight convex shape and leaves a bow which extends toward the end of the rod to further aid the debris-removing function. The strip is bent rearwardly and then inwardly on both sides, and termini of the strip are formed with abutting semi-circular recesses to engage the conduit behind the end cup.
